article page meta

Hy, on my article page meta i have:

<meta name="robots" content="index, follow" />
<meta name="keywords" content="" />
<meta name="og:title" content="" />
<meta name="og:site_name" content="" />
<meta name="og:image" content="" />
<meta name="title" content="" />
<meta name="author" content="" />
<meta name="description" content="" />
<meta name="generator" content="" />

How can i remove <meta name="og:title" content="" /> , <meta name="og:site_name" content="" /> and <meta name="og:image" content="" />

nobody knows why i have this meta on article page? or how to remove them?

Hi

Sorry, but I have no idea. Please ask this question on joomla forum. It's not template related.

It seems that the problem is TBFSocial plugin. Solved.
